I recently read that in this verse ‘power’ represents the Holy Spirit, ‘love’ represents the love of the Father and a ‘sound mind’ (self-discipline in NIV, sound mind in KJV) represents the Word of God which is Jesus Christ the Living Word. If we are in fellowship with our Father Who is Love through Jesus Christ by the power of the Holy Spirit, fear has no power over us. Oh, to walk that close to our Almighty three-in-one magnificent God!!! 🙏🏻✝️❣️
